Abstract (en)
[origin: EP0509560A2] A roll type solid electrolytic capacitor comprising a valve metal positive electrode substrate having semiconductor layers on both surfaces and electroconductive layers on the semiconductor layers is disclosed. In the process for making the capacitor, a roll-form valve metal positive electrode substrate having the semiconductor layers is immersed in an electroconductive paste, whereby an electroconductive layer composed of an electroconductive dry paste is formed in the form of being filled in every space between the adjacent semiconductor layers.
